l This invention lrelates to atomizers of the character commonly usedfor the spraying of perfumes or other toilet liqulds, and has parthepump type of atomizer.

The object of the invention is the provision of a simple, eiiicient andimproved atomlzer of this character which is small in size to adapt itto be carried in a 1purse or vanity case and which may be tight y sealedagainst leakage of its liquid contents and have its pump locked ininoperative position by the movement of a single element. The inventionis fully described in the following specification and while in itsbroader aspect it is capable of embodiment in numerous forms a preferredembodiment thereof is illustrated in the accompanying drawing, inwhich,-

Figure 1 is a top plan view of an atomizer embodyin the invention, withthe parts in sealed an locked osition. Fig. 2 is a central verticalsection o the atomizer taken on the line 2-2 in Fig. V1. Fig. 3 is a topplan view of the atomizer with the parts in usable position. Fig. 4 is aside elevation of the atomizer with a rtion in central vertical sectionand a part roken away and with the parts in the usable position shown inFig. 3, and Fig. 5 is a cross section on therline 5-5 in Fig. 2.

Referring to the drawing, 1 designates the liquid receptacle of theatomizer which is small in size and preferabl of cylindrical form withits to open to a apt to be closed by a ra hea 2 threaded therein. Thissprayea has a central vertically disposed opening'3 therethroughpreferably of tapered form to adapt it to receive a conical type of plugvalve 4, the lower end of `which has the tube 5 extending therefrom downinto the rece tacle 1 tonear its bottom. The upper end ofpthe tube 5communicates with a recess 6 in the valve 4.

The spray head 2 has a s ray discharge ich is adapted to communicatethrough a passage 8 Yin the head and a registering passage 9 in thevalve the socket 6 when the valve member is in the usable position shownin Fig. 4. The head v2 also h tending crosswisethereof and opening atits to those generally known asas an a1r passage 10 e1:-y

outer end centrally in the bottom of the discharge orifice 7 and has itsother end commumcating throu h a tube 11 with the pump member of theevice, as hereinafter described. When the valve 4 is in its openposition, a passage 12 therethrough registers at its endswith theseparated arts of the air passagel 10 and maintains suc passage open andwhen the valve is turned to its close position, the passage 12 is movedout of register with the air passage 10, thus effecting a closing ofsuch passage. Nothing new in itself is claimed 'for this construction ofatomizer.' y

The air pumping means for the atomizer comprises` a pump cylinder 13 inwhich a plunger 14 1s mounted for reciprocatory movements. This plun erhasl a stem 15 projecting upwardly thererom through the upper end of thecylinder to adapt the plunger to be-operated in one direction by theressure thereon of the thumb of a hand ho ding the device. The plungeris actuated in the opposite direction by a coiled expansion spring 16that is mounted in the bottom of the cy inderand bears upwardly againstthe plunger.

The air tube 11 extends from the atomizer head 2 down between theatomizer receptacle 1 and pump cylinder 13 and enters the pump cylinderat its lower end. In the present instance the tube 11 extends downthrough a hollow member 17 which is dis osed between the receptacle 1and pump cylinder 13 and is recessed at its opposite sides to fit thetwo members 1 and 13 which are secured thereto.

The valve member 4 has an operating arm 18 projecting laterally from itsupper end so as to adapt 1t to project over and enga e the top of theplunger stem 15 when in its depressed position to retain it in suchposition. is preferabl provided at its outer end with a ball mem er 19which is ada ted to Seat in a recess`20 in the top of the p unger stemwhen in engagement therewith, thus tending to retain the ball and stemin engagement.

e arrangement of the passages 9 and 12 in the valve 4 is such that theare turned out of register with the spray liead passages 8 To facilitatesuch action, the arm 18 I the lower end and 10, respectively, lockingengagement 15, as shown in Figs.

when the arm 18 is in with the plunger stem 1 and 2, and are in registerwith said spra head passages when the valve arm is turne to the open oroperative osition shown in Figs. 3 an 4. The swinging movement of thevalve arm 18 1s limited by a pin 21 rojecting from the valve at theouter end o the spray head 2 and coacting with o posite end walls of arecess 22 in the spray ead in which it works.

It is apparent that in the use of mivl improved atomizer, the operatorfirst t rows the valve arm 18 to the right to release it from lockingengxagement with the plunger stem 15 and to t row the plugx valve 4 intoopen relation with res ect to t e spray head passa 8 and 10. he operatormay then operate the plunger to cause a discharge of air under pressurefrom the s ray head orifice which effects a drawing up o liquid from thereceptacle through the tube 5, recess 6, an passa es 9 and 8, as wellunderstood in the art. en the operator is through using the atomizer, hemerely depresses the plunger to of its stroke and then swings the valvearm 18 to the left to effect a closing of the spray head passages and toplace the ball 19 in locking engagement with the plung- I wish itunderstood that my invention is not limited to any specificconstruction, form or arrangement of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims.

Having thus described my invention what I claim as new and desire tosecure by nited States Letters Patent is:
